Understanding the Vehicle Routing Problem (VRP)
1. Vehicle Routing Problem with Time Windows (VRPTWs) Customers often require their deliveries within a specific timeframe. This means your drivers must show up at the customer's location within the designated time window. Soft time windows: Deliveries outside this window incur penalties. Hard time windows: No deliveries can be made outside ...
Vehicle Routing Problem
In the Vehicle Routing Problem (VRP), the goal is to find optimal routes for multiple vehicles visiting a set of locations. (When there's only one vehicle, it reduces to the Traveling Salesperson Problem.) ... The response contains the travel distance (in miles and meters), and the travel duration (in minutes and seconds), between the two ...
A concise guide to existing and emerging vehicle routing problem
Vehicle routing problems have been the focus of extensive research over the past sixty years, driven by their economic importance and their theoretical interest. The diversity of applications has motivated the study of a myriad of problem variants with different attributes. In this article, we provide a concise overview of existing and emerging ...
Vehicle Routing Problem: How to Solve It
The Vehicle Routing Problem (VRP) seems simple to describe but can be tough to crack. Along with its variations like the Capacitated Vehicle Routing Problem (CVRP) and Vehicle Routing Problem with Time-windows (VRPTW), it stands out as one of the trickiest and most popular optimization puzzles in operations research.
Vehicle Routing Problem with Time Windows
These problems are known as vehicle routing problems with time windows (VRPTWs). VRPTW Example. On this page, we'll walk through an example that shows how to solve a VRPTW. Since the problem involves time windows, the data include a time matrix, which contains the travel times between locations (rather than a distance matrix as in previous ...

Travelling salesman problem
The travelling purchaser problem, the vehicle routing problem and the ring star problem [1] are three generalizations of TSP. In the theory of computational complexity , the decision version of the TSP (where given a length L , the task is to decide whether the graph has a tour whose length is at most L ) belongs to the class of NP-complete ...
An Online Approach to Solve the Dynamic Vehicle Routing Problem with
The vehicle routing problem (VRP) is a well-known combinatorial optimization problem that seeks to assign a fleet of vehicles to routes to serve a set of customers/requests [7]. Many real-world use cases of transportation agencies are modeled by the dynamic version of the problem (DVRP) with stochastic trip requests. In such
Vehicle routing problems with time windows and stochastic travel and
This paper studies a version of stochastic vehicle routing problems, in which travel and service times are stochastic, and a time window constraint is associated with each customer. This problem is originally formulated as a chance constrained programming model and a stochastic programming model with recourse in terms of different optimization ...
The Dynamic Vehicle Routing Problem: A Comprehensive Survey
The objective function of VRP is represented in Eq. 2, which aims to minimize the total travel distance.The set of constraints from 2 to 8 is defined as follows: Constraints 2 ensure that the vehicle capacity is not exceeded, while Constraints 3 ensure that each customer is visited only once by a single vehicle. Constraints 4 state that every vehicle starts from the depot.

Common Routing Problems—And How to Solve Them
The Capacitated Vehicle Routing Problem (CVRP) aims to solve this, taking vehicle restrictions into account while still solving for overall efficiency within these established parameters. Every vehicle in your fleet has maximum capacities in terms of cargo weight and volume. Failing to plan for both can have significant repercussions.
